The CBRN Respiratory System with Hood is designed to provide respiratory and facial protection in emergency situations involving potential exposure to certain nuclear/radiological, biological and chemical (CBRN/NBC) agents.

Unlike a conventional mask, the system uses a full hood combined with powered ventilation, providing a continuous flow of filtered air inside the hood. This configuration reduces dependence on achieving a direct facial seal and facilitates use by people with different facial shapes.

According to the information provided, the system is suitable for users aged 13 and over.

The wide transparent visor provides an extended field of vision, while the ventilation system helps improve comfort during prolonged periods of use.

Main Features

Powered respiratory protection

The system uses an electric blower to continuously supply filtered air inside the hood.

Positive pressure system

The airflow helps maintain positive pressure inside the hood, helping to limit the ingress of contaminants through potential minor leakage points.

Airflow up to 90 L/min

According to the information provided, the ventilation system can provide an airflow rate of up to 90 litres per minute.

Full protective hood

The hood surrounds the head and creates a seal around the neck, avoiding the need to achieve a direct seal against the face.

Compatible with different facial characteristics

The hood configuration facilitates use by people with different facial shapes and may allow use with glasses and facial hair, according to the specifications provided.

Panoramic visor

Transparent polycarbonate visor designed to provide a wide field of vision.

One size

Designed as a universal-fit system within the limits specified by the manufacturer.

Easy to put on and remove

The hood is designed for quick donning and removal in emergency situations.

Sealing System and Comfort

The hood uses a flexible construction with a peripheral seal around the neck area.

According to the information provided, the system also incorporates an internal nose mask, positioned using diagonal straps and quick-release fasteners.

This configuration is designed to help direct respiratory airflow correctly and provide greater stability during use.
